CNN's Royal Expert, Victoria Arbiter, told Shine, "Born third in line for the throne it could be sixty or seventy years before [he's ever] monarch." And that's a good thing. Arbiter points out that the time will allow him to have a relatively normal childhood, go to school, attend college, and grow up without the intense demands of being king. "William had the best deal. He did not have the same pressure as first in line for the throne, so he could do things his father wasn't able to do as easily."

Queen Elizabeth became sovereign in 1952, after the death of her father, King George IV. Now 87, she's still in good health and is expected to rule for five to ten more years. Her successor, Prince Charles, is 64 years old, so might be king for another twenty years after that. That means the royal baby's father, William, 31, may not become king himself until the middle of middle of this century. And the royals are known for their longevity-the Queen Mother lived to 101. The new prince may actually live up to a nickname making the rounds, "The King of the 22 nd Century."
